A compression system developed for venous insufficiency and leg ulcers

The product provides a low, safe resting pressure and a high, effective working pressure. This enhances the calf muscle pumping function, hence, improves the venous return and ejection fraction. The system can also be used on patients with mixed ulcers due to the low resting pressure.

The underlying bandage Lundatex® medical provides a safe and well-defined resting pressure of 20 mmHg. The PressPatch™ adheres to the bandage material without adding pressure in the resting position. However, when the patient is standing or walking the PressPatches™ creates a stiff layer, providing high effective working pressure between 45-60 mmHg.

FixPatch™ is used to close the system in the front, and is developed for the maintenance of pressure over time. This is easily done before bed rise every morning, simply by opening up and closing the FixPatch™ in the front. By opening the front, the surrounding PressPatches™ adopts to the changes in limb size, hence they provide a consistent pressure also over time.

Clinical investigation

Pilot study with Prof. Giovanni Mosti, Lucca, Italy 2016

Ejection fraction from the lower leg is severely impaired in patients with venous insufficiency and is improved by compression therapy. Inelastic compression is characterized by a high difference between resting and standing pressure and a strong massaging effect on the calf muscle, produced during movement.

Ejection fraction was measured by means of strain gauge plethysmography in 18 patients with severe venous reflux in the great saphenous vein. The procedure was performed three times in a randomized sequence: 1) in baseline conditions, 2) with the elastic bandage applied to the leg with a pressure of 20 mmHg and 3) after attaching the PressPatches™ to the elastic bandage.

“Attaching PressPatch™ to the elastic bandage, significantly improves the hemodynamic effectiveness. The improvement of ejection fraction into normal range, is due to the increase of standing pressure produced by the stiff PressPatch™ and at the same time, maintains, a low and comfortable resting pressure.”
